A ballistic pendulum is a device used to measure a bullets momentum by using a pedulum. For calculations, the acceleration due to gravity and the height of the pendulum are necessary and the theory of the conservation of momentum is used.

The change in height can be used to find velocity using the theory of conservation of momentum, since momentum is conserved.


The pendulum was just hit by a bullet. V is calculated in this way.



As can be seen from this picture, physics can be fun!
